Abstract
A method for implementing linear view-change in a BFT protocol running on a distributed system including n replicas, wherein no more than t of the n replicas are faulty, and wherein the BFT protocol enables the non-faulty replicas to agree on how to sequence execution of a plurality of service operations originating from one or more clients. The method including executing, among and by the n replicas, a phase φ of the BFT protocol, communicating instances of a lock certificate being associated with said phase; and if 2t+1 communicating instances of said lock certificate are not received by the n replicas within a predetermined timeout period, initiating a view-change with at least the following step: if said current phase φ is different than 1, each replica Psets φthe highest phase up to said current phase.
